The 2019–20 Pac-12 Conference men's basketball season began with practices in October 2019 followed by the 2019–20 NCAA Division I men's basketball season in November 2019. The conference schedule began in December 2019. This was the eighth season under the Pac–12 Conference name and the 60th since the conference was established under its current charter as the Athletic Association of Western Universities in 1959. Including the history of the Pacific Coast Conference, which operated from 1915 to 1959 and is considered by the Pac-12 as a part of its own history, this is the Pac-12's 104th season of basketball.

The Pac-12 tournament was scheduled from March 11–14, 2020 at the T-Mobile Arena in Paradise, Nevada. On March 12, the Pac-12 cancelled the tournament prior to its second round due to the COVID-19 pandemic.
